Spa PC Boards:
Circuit boards are similar to your
pc computer board. The chip is programmed to operate
a certain way and turns components on/off at certain
times and for certain reasons.

Over the years many
have asked why a board will fail. Sometimes the
failure might be caused simply over time such as
internal components failing and some even causing
damage to other components. So boards look perfectly
good yet will not operate or at least, correctly.
Some simply have components on board that fail
making the board not operate. Brownouts, blackouts,
voltage surges and spikes can cause damage to your
spa's board.

Over the years some
have tried to change only the "chip" on the board to
see if that solves the problem. The success has been
limited but if the board looks perfectly fine, it
could be the solution. More often you are simply
trying to fix the problem in the wrong way.

Most if not all boards
have settings. Easiest way to configure a new board
to work is match such things a "jumpers" from the
only to new. If you look at the boards you will see
the jumpers.

FYI:It always makes sense
to "ground" your body by touching something metal
that is properly grounded. This will avoid any
chance of a static charge damage to the new board.
